Bob is building Sunflower Valley's very first radio station! Whilst the team set to work constructing the studio, the machines think of ideas for their own radio shows but Flex struggles to think of something original. Every time he has an idea, someone beats him to it - Roley is recording a jingle, Dodger is telling jokes and Scoop and Muck are reading stories. Luckily Bob has a great idea to help inspire Flex - to find out what happens, tune in to Radio Bob!
